Hi T.,
I myself had bad allergies and asthma from about 2 weeks old. I did not get shots until I was in my 30's, and I had to have 2 (one in each arm) twice a week to start, then down to once a month after 8 years. My case was so severe, because when I was a child, a lot of doctors thought of allergies as a myth, and treating a child for them was pretty unheard of. All my folks could do was keep me away from suspected allergens, keep my room clean (without Lysol), and make sure they watched me for a bad attack. I would not be here today if my parents had not been so "unconventional" as to require that no one ever smoked in our home, brought in cats or mums or real Christmas trees. All that said, the reason for the epi pen is that when some people start their shots, their bodies treat the shot as a big pile of all the allergens they have problems with put together. They do start with weaker serum, then gradually get stronger amounts, but even a small bit could set off an asthma attack, and the epi pen is there "just in case". It is better - and cheaper - than a trip to the emergency room. Most likely though, you will not need to use it. I personally had a strong reaction to Astelin - it lowered my blood pressure. I always thought it was the shots, and it may have been them to some extent. I would feel like I had a hay fever coming on - itchy throat, eyes, etc. and I felt COLD. If your little one feels like this, and tylenol does not fix it after a couple of shots, make sure you call the Dr's office, and see if there is any problem. I waited so long, trying to tough it out, that I was really feeling bad each time. I knew that the exposure would help me if I could live through it. It did! Now, I have less allergy problems than anyone in my dept. at work. I still avoid the known things that bother me, but if I get a whiff of cut grass or perfume, I do not get hay fever now. If I had had shots when I was little, I would not be allergic to food now either. It escalates - you never grow out of them, they just go dormant, then pile on you all at once later on.
Bottom line - you are right for getting your daughter the shots now, just watch her for the first few months after them, and get the pen for peace of mind.
The Best to you guys,
D.
PS Zyrtec made me sleepy and grouchy - Claritin is the best one if you take it every day, and your brain works fine too. Wal-Mart and Walgreens both sell generic versions of it, and it is the same stuff.
